摘要
我室在5159名年龄35～64岁人中,采用特制的中空金属球吸取胃液,检测pH、OB、IgA和IgG,开展胃癌普查。检出胃液阳性者1250例,检出率为24.23％(1250/5159)。对835例胃液阳性者和87例胃液阴性者行胃镜病理检查,发现23例胃癌,均为胃液阳性者,癌检出率为0.45％(23/5159),其中早癌7例,占30.43％(7/23)。胃液阳性组癌～癌前期变化者检出率为61.32％(512/835),明显高于胃液阴性组的21.84％(19/87),经X^2检验有非常显著性意义(P<0.005)。此方法操作简单、安全病人痛苦小,癌检出率高,有一定实用价值。
pH,OB,IgA and IgG of gastric juice taken from 5159 individuals were examined for predicting cancers. The positive rate was found in 1250 cases, accounting for 24.23%. Fibrogastroscopy was conducted in 835 cases of positive gastric juice and 87 cases of negative gastric juice for pathological examination. The 23 cases of gastric cancer detected was from the group of the positive gastric juice, accounting for 0.45％ of all the people. 7 cases were early cancers with rate of 30.43%. The rate of cancer and precancerous change detected in the gastric juice positive group was 61.32％, significantly higher than that of the negative one. The method was proved to be reliable, accurate and practical.
